Think it'll work? *crickets*
If you live in a state where the outcome of the presidential election is not in doubt, then voting for a third-party candidate is a sensible idea.
And when enough people in that "safe" state vote for a third-party candidate, suddenly the state isn't quite so "safe" any longer. Remember Brexit?
In an interview on BBC’s Victoria Live, one man who voted "Leave" said, "I didn’t think my vote was going to matter too much because I thought we were just going to remain."
The man, who was introduced as Adam, said he is now "worried" because he assumed "Remain" would win. He added, "I think the period of uncertainty that we’re going to have for the next couple of months — that’s just been magnified now. So yeah, quite worried."
